Hardware cloth on the ground around the pen too.
You could also do an electric fence around any area you choose.
It took me a small amount of time to get on the electric fence train. The last straw was finding broken zip ties(thankfully I did not only use zip ties). They were focused on one area by the ducks. Since I put the fence up i have not found any more broken zip ties. When I got to the gate with the electric fence there was claw marks and dried blood, I had left exposed hardware cloth in case sonething attempted to reach in and they did.
I have a family of raccoons and opossums living about 25 ft from the coop in the trees--many sleepless nights. The run is hardware cloth from top to bottom, heavy duty netting on top, hardware cloth on the ground 2 ft out all the at around plus the electric fence all around and on two sides on the top(you know in case they jump from a tree or the top of the fence.
